Behind Finch's two top scores, Maxwell is next on the all-time T20I record list after he belted an unbeaten 145 against Sri Lanka in 2016.
He plundered 16 fours and 10 sixes in the highest individual innings in T20 worldwide cricket, which only ended when he overbalanced chasing a wide one and hit wicket off the penultimate delivery of the innings. D'Arcy Short contributed only 46 runs (off 42 balls) to the world-record opening stand of 223.
Finch's 172 left him three short of Chris Gayle's highest-ever T20 innings which he made for Royal Challengers Bangalore in the Indian Premier League five years ago, against a Pune Warriors side captained by Finch.
Finch's innings helped Australia post a mammoth total of 229/2 in their 20 overs.
Aaron Finch surpassed his own world record high score of 156 in T20Is with his ninth six en route 172 off just 76 balls courtesy 16 fours and 10 sixes.
2 - Aaron Finch reached his second T20I 150.
Australia took 75 from the Powerplay, with Finch doing the bulk of the scoring while fellow opener D'Arcy Short was content to turn the strike over to his big-hitting partner.
His knock against the Zimbabwe cricket team on Tuesday means he now holds the distinction of having the highest global score in worldwide Twenty20 cricket.
Finch's previous record knock stood for almost five years: 156 off 63 against England at Southampton in 2013.
